Freshwater FAQs
What’s the best starter fish for a freshwater tank?
Popular beginner choices include guppies, platies, tetras, and bettas. They’re hardy and easy to care for.
How many fish can I keep in my tank?
A common guideline is “one inch of fish per gallon of water,” but this varies depending on species and filtration.
Do I need live plants in a freshwater tank?
No, but live plants help with oxygen and water quality, while artificial plants provide easy decoration.
How often should I change the water?
Partial water changes (20–30%) are recommended weekly to keep water clean and healthy.
Can freshwater fish live with saltwater fish?
No — freshwater and saltwater fish require completely different environments.
